JOSEPH R. HOOKER, OF CARTHAGE, MISSOURI.

BED-SPRING.

To all whom it may concern:

Be it known that I, JOSEPH R. HOOKER, a citizen of the United States,residing at Carthage, in the county of Jasper and State of Missouri,have invented a new and useful Bed-Spring, of which the following is aspecification.

This invention relates to bed springs and its object is to provide anovel arrangement of helical springs and means for connecting the samewhereby the upper face of the bed spring, which is the one contacted bya mattress, is rendered free of all sharp projections and angles liableto cut into and tear a fabric bearing thereon.

Another object is to provide novel means for tying the various coilstogether so as to positively prevent displacement thereof in anydirection.

Another object is to provide a bed spring in which the number ofseparate tie devices utilized is reduced to the minimum, the greaterportion of said tie devices being formed integral with the coils.

With these and other objects in view the invention consists in certainnovel details of construction and combinations of parts hereinafter morefully described and pointed out in the claim.

In the accompanying drawings the pre ferred form of the invention hasbeen shown.

In said drawings: Figure l is a perspective view of a portion of a bedspring constructed in accordance with the present invention. Fig. 2 is adiagrammatical view showing in plan the relative positions of theopposed series of helices and the diagonal and longitudinal braces. I

Referring to the drawings by characters of reference 1 designates theupper frame and 2 the lower frame of the bed spring, the said framesbeing preferably formed of metal rods bent into proper shape, one beingdisposed directly above the other. Parallel rows of spring helices aredisposed within and between these frames as indicated at 3, andconnecting opposite portions of the frame 2 are brace wires 4, each wireextending along the edge portion of one row of helices and beingprovided adjacent each helix with a substantially U shaped crimp 5.These crimps are extended horizontally and each receives the base of ahelix, which base is in the form of a rin 6, formed by bending the lowerwhirl o the spring in a reverse direction. The terminal of this ringSpecification of Letters Patent. Patented June 21, 1910.

is looped around the fold 7 in the lower whirl so as to form an eye 8and the ring 6 is provided at a point diametrically opposite this eyewith a crimp 9 located within the crimp 5 in the adjoining brace wire 4.Those of the springs arranged along one side of the frame 2 have loops10 extending from the eyes 8 and these loops engage the frame. Theintermediate rows of helices however have stems 11 extending from theeyes 8, each stem projecting over the crimp 5 and under the crimp 9 andterminating in a hook 12 which extends under the crimp 5 and thenceupwardly in the direction of the frame 1. It will thus be seen that thebase portions of all of the helices together with the wires 4 aresecurely tied together without the necessity of utilizing separate tiedevices. All the helices at one side of the center of the bed spring arearranged in the same manner and with their eyes 8 and stems 11 locatedat the same side. Those at the other side of the longitudinal center aresimilar in all respects to the helices heretofore described but areoppositely disposed so as to bring the crimps 9 thereof at those sidesof the helices nearest the longitudinal center of the bed spring. Twowires 4 are arranged between the two adjoining series of oppositelyarranged springs, the crimps 9 of the said springs being disposed withinthe crimps 5 of the wires, and inasmuch as there are no stems upon thesprings which are available for tying said springs together at thesepoints, it is necessary to utilize links 13 having hooked ends 14 whichproject under the crimps 9 and through the crimps 5, with theirterminals projecting upwardly in the direction of the frame 1. In otherwords, these hooked ends are disposed in the same manner as are thecorresponding ends of the stems 11 heretofore described.

The upper frame 1 is provided with cross tie wires 15 and longitudinaltie wires 16, all of said wires being provided at their intersectingpoints with depressions 17 resting one within the other, the transversewires 15 being formed at opposite sides of their depressions withupstanding crimps 18, between which rest the hooked upper ends 19 of thehelices 3. These hooked ends rest within the depressions 17 in thetransverse wires 15 and between the upstanding crimps 18, said endsextending under the longitudinal wires 16 and having their terminalsprojecting downwardly in the direction of the frame 2. It Will beapparent that by connecting the springs to the tie Wires in this mannerit is impossiblefor them to become displaced either in the direction ofthe Width or of the length of the frame. However, if desired, additionalmeans, such as diagonal braces 20, may be utilized. These braces arelocated upon the middle portion of the bed bottom as shown in Fig. 2 andhave their ends provided with hooks 21, Which are so arranged as toengage both the upper whirls of the springs and the adjoining tie Wires.

It is of course to be understood that various changes may be made in theconstruction and arrangement of the parts without departing from thespirit or sacrificing the advantages of the invention.

WVhat is claimed is A bed spring including a frame, spaced helices eachhaving an unbroken base ring through said U-shaped extension and under30 the offset portion of the base ring, the hook of the stem engagingone side of the said U- shaped portion of the tie wire.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signatur 5 in the presence of two Witnesses.
